FCC-ee Machine Detector Interface Alignment System Concepts / Watrelot, Leonard
This thesis is in the framework of the lepton collider part of the Future Circular Collider project, aiming to be the next flagship project at CERN after the High Luminosity upgrade of the Large Hadron Collider, in 2040. The study focuses on the alignment, and monitoring of the alignment, of some accelerator components located inside the physics detector, close to the collision point. [...]

X-Ray Absorption Spectroscopy to Investigate Precipitated Oxides in Nb3Sn Wires With an Internal Oxygen Source / Bovone, G (Geneva U.) ; Buta, F (Geneva U.) ; Lonardo, F (Geneva U.) ; Bonura, M (Geneva U.) ; Borca, C N (PSI, Villigen) ; Huthwelker, T (PSI, Villigen) ; Hopkins, S C (CERN) ; Ballarino, A (CERN) ; Boutboul, T (CERN) ; Senatore, C (Geneva U.)
Internal oxidation can achieve significantly enhanced Jcin Nb3Sn wires, but the mechanism of oxygen transport and oxide precipitation is not fully understood. Our investigation employs X-ray Absorption Near-Edge Structure (XANES) spectroscopy, revealing insights into the oxidation of Zr and its interaction with oxygen in different areas of the wire cross section. [...]

Influence of the Heat Treatment on the Layer JC of Internal-Sn Nb3Sn Wires With Internally Oxidized Nanoparticles / Lonardo, F (Geneva U.) ; Bovone, G (Geneva U.) ; Buta, F (Geneva U.) ; Bonura, M (Geneva U.) ; Bagni, T (Geneva U. ; Uppsala U.) ; Medina-Clavijo, B (CERN) ; Ballarino, A (CERN) ; Hopkins, S C (CERN) ; Boutboul, T (CERN) ; Senatore, C (Geneva U.)
We evaluated various heat treatments (HT) for maximizing the Nb3Sn layer thickness while retaining a refined grain microstructure in low filament count internal-Sn Nb3Sn Rod-In-Tube wires with internally oxidized nanoparticles. These wires were manufactured in our laboratory using SnO2as oxygen source and Nb alloys containing Ta and Zr or Hf. [...]
